Implication

Age independently drives HRV decline beyond VO2peak or BMI; leaves open causal mechanisms and interventional targets for longitudinal study.

Population

164 healthy normotensive adults (75 men, age 20-87 yr) from the Baltimore Longitudinal Study on Aging

Outcome

Heart rate variability (HRV) components: respiratory sinus arrhythmia (RSA; 0.12-0.40 Hz) and 0.10-Hz variability (0.06-0.10 Hz) extracted from 8-min electrocardiogram recordings in the supine, seated, and standing posturessurrogate

The age-associated decline in heart rate variability is primarily driven by age itself rather than secondary changes in aerobic capacity or body mass index.
